A national group representing Canada’s professors and instructors is urging them to stay out of the US unless the trip is critical.
The Canadian Association of University Teachers (CAUT) issued updated advice on Tuesday, saying it “strongly recommends” that academic staff travel to the US “only if essential and necessary.”
The warning comes as the political climate south of the border grows more unpredictable.
It singles out several groups who should think twice before boarding a plane, such as professors from countries that could be targeted by a future travel ban, researchers whose work clashes with US policy, and anyone who has criticized the Trump administration online.
Professors who are transgender, or whose passports show recent travel through nations at odds with Washington, are also on the list.
CAUT executive director David Robinson says the advice aims to protect academic freedom.
“Border scrutiny now extends beyond luggage to laptops and ideas,” said Robinson.
The advisory follows a federal notice two weeks ago telling Canadians bound for the US to expect tougher questioning and searches of electronic devices.
Ottawa also warned that travellers refused entry could be held while awaiting deportation.
In March, a French scientist was denied entry to the US after criticizing US research rules, according to France’s education ministry.
Until the climate settles, CAUT urges remote participation in conferences and meetings.
“Review your options and travel only if you must,” said Robinson.
